If you’re like most iPhone users, you probably don’t use NFC all that often. But if you want to turn it on, there’s a pretty simple process. Here’s how to do it:

  1. Open the Settings app on your iPhone 7.
  2. Tap on “General.”
  3. Under “Accessibility,” tap on “NFC.”
  4. If you have an NFC-enabled accessory, turn on “Enable NFC.” If not, just leave it off. (You can always enable it later if you want.)
  5. Tap on the “NFC” button to turn it off or on, depending on your preference. ..
